GENERAL INFORMATION
INTRODUCTION
Vehicles equipped with the Vehicle Theft Security
System (VTSS) system, the doors, liftgate, hood and
ignition circuit are monitored by the Body Control
Module (BCM) when the system is armed. The VTSS
will prevent the engine from starting until the BCM
receives a disarm signal. If the VTSS is triggered,
the horn will pulse, headlamps/marker lamps will
flash, and the VTSS warning lamp will flash. If BCM
determines the threat to be false and the VTSS is not
triggered again, the system will shut down and
rearm itself after three minutes. The VTSS monitor-
ing portion of the system is split into two sections.
The engine compartment section and the passenger
compartment section. If a malfunction occurs in the
engine compartment section, the passenger compart-
ment section would still arm and function normally.
If an electrical malfunction occurs in either section of
the system a Diagnostic Trouble Code (DTC) would
be stored the BCM memory to aid system repair.
DTCs can be retrieved using scan tool (DRB)
attached to the diagnostic connector above the accel-
erator pedal.
ENABLING
To initialize the VTSS feature the operator must,
with the engine compartment hood open, cycle the
key in the liftgate key cylinder to the unlock position
giving the BCM a disarm signal. At this time the
visual alarm outputs the headlamps and marker
lamps will function. However the audio alarm output
the horn and engine disable portion of the VTSS will
not function until there has been twenty consecutive

If during alarm being set the BCM receives a
request from the RKE module to enter PANIC mode
the BCM will cancel the alarm, return VTSS armed
state and then perform the RKE PANIC feature.
DESCRIPTION AND OPERATION
ARMING PROCEDURE
METHOD-A
(1) With the key removed from the ignition lock
and any door open, actuate one of the following:
• Power door lock button to LOCK,
• Key fob LOCK button
• Door lock key cylinder to locked position.
(2) Close all opened doors.
(3) After the last door is closed, an arming time-
out period of sixteen seconds will start, then the
VTSS will become armed.
METHOD-B
Actuating the key fob transmitter LOCK button,
key locking the front doors or liftgate with the doors
closed and the ignition locked will begin the arming
time-out period. If method-A, 16 second time-out
sequence was in process when method-B was actu-
ated, the 16 second time-out will restart from the
time of the second actuation.
If the security lamp does not illuminate at all upon
final door closure, it indicates that the system is not
arming.
The current VTSS status armed or disarmed shall
be maintained in memory to prevent battery discon-
nects from disarming the system.
